Abstract
A device for detecting gaseous and vaporous components of a gas mixture by means of channels , which are located next to each other on a support , are connected in parallel in terms of flow, and are exposed to the component to be detected along a flow axis . A scanning section of a scanning device is provided which extends along one of the channels , for detecting the change in color of reaction zones in the channels . Multiple channel arrangements can also be analyzed in a simple manner with a scanning section evaluating individual channels. At least some of the channels on the support are directed such that an angle &agr; not equal to 0 is formed between the flow axis and the scanning section , and the channels are located in the covered area of the scanning section
